DS who is 3 has lots of really nice picture books now which have plenty of words on each page and lots of meat in the story, it seems to me. He's just starting to read longer books too, so how long will the little thin picture books last?
Reason I ask is because I prefer to store paperback picture books on bookcases where the covers face the front (as there's next to no spine to identify the book on a normal shelf). I want to buy yet another bookcase that holds books this way, and wondering how long it's going to be needed?
